fluid and interferes with the voperation of thev pump. During the pumping operations it often becomes necessary to pull the sucker rod. It is a prime object of this invention to provide an attachment for the rod that will automatically y clean the tubing when the rod is withdrawn for repairs or replacements to the pump.

With the above and other objects in View the invention has particular relation to certain novel' features of construction, arrangement of parts and use, an example of which is given in this 1 specification and illustrated inthe accompanying drawing wherein:

Figure '1 shows a vertical sectional view of a pump tubing showing the sucker rod having the improved attachment applied thereto.

Figure 2 shows an elevational view of the cleaning attachment.

Figure 3 shows an .elevational view taken at right angles to the .view shown in Figure 2.

Figure 4 shows an end view. Figure 5-shows a cross-sectional view taken on the line 5-5 of Figure 3 illustrating a method and means for, clamping the attachment to the rod, and

Figure 6 shows a cross-sectional view showing the attachment as clamped to the sucker rod.

, Referring now moreparticularly to the drawing wherein like numerals of reference designate similar parts in each of the gures, the numeral I designates an elongated body substantially cylindrical in general contour and preferably formed of hard wood. The lower end of the body is tapered downwardly, as at 2, to form a guide.

The body has a deep groove 3 extending from end p to end thereof to receive the sucker rod 4 through which the traveling valve of the pump isoperated in the well known manner. l As more clearly illustrated in Figure 5, the sides of the groove 3 converge outwardly so that the sucker rod will require the application of force thereto in order to become seated in the groove 3,.. the sides of the groove being spread apart slightly '5 5 as the rod is seated in the groove .and thereby the rod is very tightly gripped when once seated in place. Preferably one of said attachments I will be secured on each section of the sucker rod with the lower end of the guide 2 resting against the enlargement 5 at the lower end of said section. 5 For the purpose of additionally securing the attachment I to the rod I, heavy staples such as l may be fitted around the rod and their arms. passed through the bearings 1, l, as illustrated in Figures 3 and 5. When the staples are drawn 10 closely about the rod 4, as shown in Figure 6, the free ends of the arms may be turned outwardly into thevgrooves 8 and cut oli:` as illustrated in Figure 6, thus forming a secure anchorage of the attachment `to the sucker rod. 15 The outer portion of the groove 3 will provide a channel for the upward passage of the oil being pumped', said oil passing on up through the pump tubing 9 to the ground surface. The body I is also provided with the external verticalchannels 20 I0, I0, to provide additional space for the upward-passage of the pumped liquid.

The sucker rod 4 is reciprocated up and down to operate thetraveling valve of the pump in the well known manner. As will be noted, the 25 upper end of the body I lits closely within'the pump tubing 9 and presents a cutting or scraping corner I I which scrapes .the paraffin oi of the inner Walls of the tubing as the pump reciprocates. At times it becomes necessary to pull the so pump, in which case the sucker rod 4 is'usually removed, an'd as it is pulled out the upper ends of the bodies I spaced along the sucker rod will scrape and cleanse the inside wall' of the tubing.

There will usually be a number of the attach- 35 ments or bodies I spaced apart along the sucker rod and the verticalgrooves of one will be staggered with respect to the corresponding grooves of others so that the entire area of the inside wall of the tubing4 will be scraped and cleaned 40 during the removal'of the sucker rod from the tubing.

The drawing and description disclose what is now considered to be a preferred form of the invention by way of illustration only while the 45 shaped to clamp around a rod in the groove and l comprising an elongated body whose upper end presents a tubing scraper,'said body being approximately cylindrical in general contour and having a deep groove extending from end to end thereof to receive a sucker rod, said body having transverse bearings on opposite sides of the groove, a staple shaped to clamp around a rod in the groove and Whose arms are tted through said bearings, the free ends of the staple having stops to prevent the detachment of the staple m from said bearings.
